Diagnosis. This species belongs to the femoralis   complex (see diagnosis of B. femoralis   ), species of which are difficult to distinguish except by aculeus shape. That of B. zumbadoi   differs from those of B. osmundsonae   and nigrifemur   in having the tip stouter (lobed part less than half as long as wide) and not rounded proximal to the lateral lobe. The lobes, particularly the lateral one, are larger than in B. biseriata   and they are blunter than in B. cyclantherae   , but the gaps are shallower than in B. femoralis   which also has a rounded medial lobe. The scutellum, in lateral view, sometimes has a ventrobasal brown mark, a character state that also occurs rarely in B. femoralis   but is otherwise unknown in the complex.

Description. Head: Dark brown area on ocellar tubercle extended almost to postocellar seta. Medial vertical seta in yellow area. Medial occipital sclerite with pair of dark brown submedial vittae on ventral half. Occipital suture narrowly dark brown, on lateral side bordered by slightly paler, wedge-shaped area, broader dorsally, just reaching postocular setae and sometimes almost reaching lateral vertical seta.

Thorax: Postpronotal lobe entirely yellow or with minute brown spot at junction with anepisternum. Scutum with 2 pairs of dark brown vittae; submedial vitta narrowed slightly posterior to transverse suture and connected to or narrowly separated from mark on posterior margin; sublateral vitta narrowly interrupted at transverse suture, narrowly separated from mark on posterior margin; posterior margin with 1 broad brown mark, narrowed medially. Notopleuron dark brown except small yellow area surrounding posterior seta. Small brown spot anterior to postsutural supra-alar seta, brown vitta anterior to postalar seta, and brown spot lateral to dorsolateral corner of scutellum present. Scutellum with pair of large submedial brown marks or single inverted U-shaped medial mark on disk usually extended to basal margin; side with or without small faint brown spot to moderately large dark brown L-shaped mark on ventrobasal margin. Subscutellum and mediotergite with pair of dark brown vittae, ventral half of lateral margin of mediotergite also narrowly brown, sometimes connected to vittae ventrally. Pleuron mostly dark brown, yellow only on propleuron, part of anepisternum (with large dorsomedial dark brown spot extending ventrally at least 2/3 distance to ventral margin, and broadly dark brown in posteroventral corner), extreme anterior and posterior corners of katepisternum, all of katepimeron, greater ampulla, narrow dorsal, posterior and ventral margins of anepimeron, and narrow anterodorsal margin of anatergite. Basalare brown. Dorsocentral seta aligned slightly anterior to postalar seta.

Legs: Mostly yellow. Mid femur with anteroventral and posteroventral brown marks on apical 1/5–1/4. Hind femur with entire apical 1/4–1/3 dark brown.

Wing ( Fig. 78 View FIGURES 76–83 ): Length 7.80–8.25 mm, width 3.70–3.80 mm, ratio 1.99–2.20. Crossvein r-m at 0.54–0.62 distance from bm-cu to dm-cu. Cell c with 2 broad rectangular hyaline spots, both reaching costa and subcosta; medial brown area almost as dark as area of cell r1 posterior to pterostigma, sometimes paler medially, distinctly narrower than both hyaline spots. Pterostigma with large subapical hyaline spot [#3] reaching R1. Cell r1 basally (proximal to apex of R1) with 2 pale brown to hyaline spots (occasionally fused into 1 elongate mark); cell r2+3 with 1–2 spots. Radial cells medially with 1 very broad quadrate basal hyaline mark [#5 fused with additional spot?] in cell r1, sometimes partially divided posteriorly by pale brown spot; cell r2+3 with 2 broad to very broad hyaline spots [#8, #9] posterior to r1 mark, both broadly reaching R4+5; cell r4+5 with broad hyaline spot [#14] aligned with r1 mark, extended from R4+5 slightly more than halfway across cell, and with medial hyaline spot [#15] near anterior end of dm-cu small; sometimes with small to minute anterior hyaline spot [#48] near midlength not touching vein R4+5. Distally cell r1 with 1 marginal subapical hyaline spot [#6]. Cell r2+3 with 2 marginal ovoid hyaline spots and subapical spot posterior to proximal spot [divided #10, #11], and sometimes with 1–2 minute more proximal spots. Cell r4+5 with small hyaline spot [#16] anteriorly, aligned with more proximal or between apical marks in cell r2+3; with 1–2 large ovoid posterior hyaline spots aligned with hyaline marks in cell m; and with 2 ovoid or 1 bilobed marginal or submarginal hyaline spots [#18, #18A]. Cell m without subbasal hyaline spot [#49] near midlength of dm-cu; with 2–3 marginal hyaline spots, proximal and distal spots [#27, #29] large, medial spot [#28] very small if present, and 1 large anteromedial spot [fused #26, #26A], narrowly separated from proximal marginal spot; distal and anteromedial spots narrowly and faintly separated from vein M. Cell br with subbasal hyaline spot [#12]. Cell bm with circular subbasal and subapical hyaline spots [#19, #20]. Cell bcu with large hyaline spot in lobe. Anal lobe hyaline except brown area from apical part of lobe of cell bcu and base of vein A1+Cu2 crossing apex of vein A2, occasionally (1♂) with small brown submarginal spot medially proximal to A2. Posteromedial part of wing with large broad hyaline area; cell br with subapical hyaline spot [#13] and sometimes with smaller more proximal spot [#44], sometimes fused into 1 broad spot; cell dm with broad and long hyaline area [fusion of at least #51, #52, #21, #22, #23, #24, #50], sometimes narrowly or partially divided by pale brown medially, tapered distally, extending farther posteriorly than anteriorly; cell cu1 medially with broad anteriorly trilobed and posteriorly 1–3 lobed mark [fused #31, #32, #33, #36, #36A, sometimes #34] or with more broadly fused area with 2 anterior and 1–3 marginal brown spots, broad on posterior wing margin, proximally connected to or narrowly separated from mark [fused #34, #39] across vein A1+Cu2; subapical marginal hyaline spot [#37] reaching vein Cu1. Cell dm with anteromedial subapical hyaline spot [#25] and with posterior hyaline spot proximal to level of subapical mark in cell cu1 and connected to proximal hyaline area.

Abdomen: Syntergite 1+2 with pair of isolated submedial brown spots and pair of irregular posterolateral brown marks. Tergites 3–5 with pair of isolated submedial brown spots, anterolateral brown spots, sometimes isolated, and pair of irregular lateral brown markings formed from connected submedial spots and L-shaped posterolateral bands, sometimes connected to anterolateral spots.

Aculeus ( Fig. 145 View FIGURES 136–145 ) 0.77 mm long, 1.71 times as long as wide, with acute scales dorsally and ventrally on membrane medially; tip bluntly angulate basolaterally, short triangular (lobed part 0.45 times as long as wide), with small, truncate, slightly notched medial lobe and 3 pairs of step-like lobes separated by relatively shallow gaps, that between sublateral and submedial lobes deeper; sublateral lobe larger than submedial lobe; lateral gap 1.05 times as long as wide. Spermathecae subspherical, with slightly convoluted, slender sclerotized neck and large cylindrical basal apodeme.

Etymology. The name of this species is a noun in the genitive case in honor of Manuel Zumbado, the collector of the holotype, who is among the most prolific collectors of flies in Costa Rica.

Biology. No specimens have been reared to determine the host plants of B. zumbadoi   . One adult was collected on a mixed patch of Cyclanthera langei Cogn.   (95CR14) and a Sechium species   at San Gerardo de Dota, Costa Rica (also see Biology section).
